Song sung in the most languages by one artist/group
According to Official Guinness Records,
The song sung in the most languages by one individual is 'Golden Dreams of Gandhiji' by Dr. Kesiraju Srinivas, a.k.a. Ghazal Srinivas (India), who recorded the track in 125 different languages and released it as a double CD album entitled 'The Path of Mahatma Gandhi' on 2 December 2009. The languages include Amharic, Bengali, Croatian, Danish, Esperanto, Fijian, Greek, Hebrew, Italian, Japanese, Kashmiri, Lengmai, Malay, Nepali, Oromifa, Polish, Russian, Sanskrit, Tagalog, Uzbek, Vietnamese, Wolof and Zulu. The only letters of the alphabet not covered are: Q, X and Y, so if Dr. Srinivas recorded the song in Qashqa, Xhosa and Yiddish he would have a full house.
